Depending on the regional's you used to, the championship is like 6-8 regionals divided into 4 divisions.

Last year each division had 88 teams. In comparison the largest regionals this year had 66, most somewhere around 45. That's a lot of teams.

Now if you add the 200 other FTC, FLL, and jrFLL teams then you might get an idea for the true size of the FIRST Championship.

The dome is big enough to hold 5 FRC, 4 FTC, 8 FLL fields, and all the spare field equipment with room to spare. The adjacent convention center can hold the same but with 550-10'x10' team pits, sponsor display area's, and FIRST information booths, with a little room to spare.

In short, the championship is huge.
